摘　　要：随着城市化进程的加快,大型基础设施项目日益增多,钢筋混凝土超长挡墙作为重要的支护结构,其施工质量直接影响工程的安全与稳定。论文研究了钢筋混凝土超长挡墙无缝施工的新工艺,旨在通过优化设计与施工流程,提高挡墙结构的整体性与耐久性。新工艺采用膨胀混凝土与加强带技术,取消永久性变形缝,通过膨胀混凝土的补偿收缩性能控制裂缝产生,实现超长挡墙的无缝施工。研究内容包括工艺原理、材料选择、配合比设计、施工工艺流程及操作要点,为类似工程提供技术参考。With the acceleration of urbanization and the increasing number of large-scale infrastructure projects,the construction quality of reinforced concrete super long retaining walls,as an important supporting structure,directly affects the safety and stability of the project.The paper studies a new technology for seamless construction of reinforced concrete super long retaining walls,aiming to improve the overall integrity and durability of the retaining wall structure by optimizing the design and construction process.The new technology adopts expansive concrete and reinforcement strip technology,eliminates permanent deformation joints,and controls crack generation through the compensating shrinkage performance of expansive concrete,achieving seamless construction of ultra long retaining walls.The research content includes process principles,material selection,mix design,construction process flow,and operational points,providing technical references for similar projects.
